What type of database? (SQL server 20xx? Mysql? Sqlite?)

What node are you using? (Full name please e.g. node-red-contrib-xxxxx)

Hi,

I am using PostgresSQL database.

Node - node-red-contrib-postgres-multi.

According to the readme you need to format the payload in a particular way.

Try adding a function node and put this code in (you will need to modify the SQL)...

msg.payload = [
    {
        query: 'insert into mytable (message) values (1, $p1)',
        params: {
            p1: msg.payload
        },
    },
];
return msg;

Hello,

I tried same but not working.

Below is my Write SQL query program. which i have done in function node.
msg.payload value is unsigned8 bit (ex. 13 or 234 etc).

var timestamp = new Date().getTime();
var name = "Sensor1"
var value = msg.payload;

if (flow.get("Start")===true){
msg.payload = "INSERT INTO table1 VALUES("+timestamp+","+name+","+value+")";

return msg;
}

↑ That is nothing like the correct format. Did you read my post or open the "readme"?

This should get you closer to a solution...

var timestamp = new Date().getTime();
var name = "Sensor1"
var value = msg.payload;
msg.payload = [ 
  { query:`INSERT INTO table1 VALUES(${timestamp},'${name}',${value})` } 
];
return msg;
